Hi. I'm new to this site and clueless about AV and hoping someone can help. I had to get a new projector to replace an old one (Sharpvision) that died. I bought an Epson 5030. The previous homeowner had built our entire media room himself and has it all very customized which is confusing to me. He had a trigger wire that ran from the screen to the projector so when the proj was turned on, the screen auto comes down. The prob I have is that the plug that goes into the projector doesn't fit in the "trigger output" hole of my new Epson proj. It looks like he spliced some 12v input to + and - speaker wire that must connect to the screen (not accessible to see from the attic). So I can only think to try and find the right kind of plug that will fit into the proj and splice it to replace the current one. Anybody have idea?
